SPECIFICATION forming part of Letters Patent No. 783,991, dated February 28, 1905. Application filed March 2, 1901. Renewed December 19, 1904. Serial No. 237,469.

To (1W. loll/om, it may concern/.-

Be it known that 1, FuANcIs BILLING HAM, a citizenof the United States, residing at N o. 9.67 South Second street, Brooklyn borough, New York city, county of Kings, and State of New York, have invented a new and useful Improvement in Side Reflectors, of which the following is a specification.

My invention relates to side reflectors for \Velsbach or other burners in which light is concentrated at a focal point, behind and above which the reflector is arranged, the object be ing, lirst, to produce a reflector which while illuminating any place where a strong light is desiredsuch as the pin end of a bowling-ah ley, a rifle range, etc. -will permit the observer to remain in the shadow, the rays of light being thrown in a direction away from the bowler or any person at the back of the reflector, and, second, the construction of such a reflector in which the reflecting parts will be easily accessible forcleaningand repairing. I accomplish these objects by constructing a reflector, shown in the accompanying drawii'igs, in which---- Figure 1 is a side elevation, the reflector being shown in section. Fig. 2 is a front elevation of myin vention. Fig. 3 is an enlarged detail view of one of the spring-clips.

Similar characters of reference refer to similar parts. i

The reflector is attached to a gas-fixture by an elbow 1, into which a long nipple 2 is screwed. An L burnencoek 3 is screwed on the free end. A by-pass (so called in the trade) l is screwed on the nipple under the burner 5. The reflector proper consists of a round concave central reflector 6, preferably spun of metal. Soldered to the periphery at a suitable angle is a truncated cone 7, of sheet metal. This cone is securely fastened to the nipple 2 by an arm 8, which holds the reflector rigidly at a predetermined angle. \Vithin the cone part of the reflector strips of plain or fluted mirror-glass 9 are fastened. I prefer to turn over an inner edge 10 on the outer edge of the cone, behind which the glasses are slipped and held in place, the inner end of the glasses being held by means of clips 11 or other simple means. A hood 12 is fastened 5 on the upper half of the cone for the purpose of deflecting downward the rays thrown out by the reflecting-surface. in this manner all the light yielded'by the burner is thrown out and downward. Thehood maybe detachably fastened in place by means of spring-clips 13. it is preferably made of corrugated sheet metal, the inner surface of which is bright or polished. An opening l/i is left in the cone for tlie nissage of the burner-chiumey 15. A neck and canopy (not shown) may be used to prevent heat striking the ceiling in low rooms.

It is obvious that an electric incandescent lamp of high candle-power can be used instead of the gas-burner, the result as regards the 5 light-reflecting qualities being substantially the same as when a gas-burner is used.

In constructing the reflector with an arm or brace, as spcci lied, a determined angle is maintained, and should any of the glasses become 7 O useless through heat or breaking it may be removed and a new piece inserted very quickly.

To assist in supporting the reflector upon a fixture, chains 16 may be attached to the reflector and fastened to the ceiling.

Such being the construction, the operation is as follows: The reflector having been fitted either to a bracket or pendant, in the case of gas being used the gas-burner is adjusted for lighting in the usual way, the gas turned on at the cock, and the gas is ignited. A powerful light CODCODlJI'fttOtl on any given point is the result. If it is desired to lower the light, one arm of the by-pass is pulled down, which permits a small flow of gas to pass through it 5 to the burner, burning only a small flame. \Vhen it is desired to illuminate the objective point, by pulling on the other arm of the bypass the full flow of gas is permitted to pass through to burner, and the reflector is illu- 9 minated. hen it is desired to shut olf the gas entirely, the gas-cock 3 is turned olf.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

A device of the type set forth, comprising ing' spring-clips for engagement With the upper edge portion of the reflector, with means for supporting the upper portion of the reflector, and a concave reflector inclined downwardly and secured to the smaller end of the frusto conical reflector, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses, this 25th day of February, 1901.

FRANCIS BILLINGHAM.
